Trigger Finger: Overview

What is trigger finger?

Trigger finger is a condition in which a person’s finger or thumb gets stuck in a bent position and then straightens with a snap, much like a trigger being pulled and let go. If trigger finger is severe, the finger may become locked in a bent position.

Who gets trigger finger?

The cause of trigger finger is not exactly known. There is a theory that repetitively falling on an outstretched hand could cause irritation and inflammation of the tendons that might eventually lead to trigger finger. Kids and adults with hobbies or work that require repetitive gripping actions are also more susceptible.

More females are seen with trigger fingers than males. People who are at greater risk may have other medical conditions such as diabetes.
